Answer: 96in²

Step-by-step explanation: To find the volume, you multiply the Length, Width, and Height.

The formula is whl, which means W × H × L.

So, we'll multiply 8 by 1 by 12.

Step 1.

Multiply 8 by 1.

8 × 1 = 8

Step 2.

Multiply 8 by 12.

8 × 12 = 96

Hence, 96in² is the answer.

What is the area of the model in the problem?

nata0808 [166]

Answer:

$A=x^2+12x+27\ units^2$

Step-by-step explanation:

we know that

The area of the model is equal to the area of a rectangle

The area of a rectangle is equal to

$A=LW$

we have

$L=x+9\ units$

$W=x+3\ units$

substitute

$A=(x+9)(x+3)$

Apply distributive property

$A=x^2+3x+9x+27$

Combine like terms

$A=x^2+12x+27\ units^2$

Given:

Compound shape

To find:

The area of the compound shape.

Solution:

The compound shape is splitted into two parallelograms.

Bottom parallelogram:

Base = 7.5 cm

Height = 5 cm

Area of the parallelogram = base × height

= 7.5 × 5

= 37.5 cm²

The area of the Bottom parallelogram 37.5 cm².

Top parallelogram:

Base = 7.5 cm

Height = 4.5 cm

Area of the parallelogram = base × height

= 7.5 × 4.5

= 33.75 cm²

The area of the top parallelogram 33.75 cm².

Compound shape = 37.5 + 33.75

= 71.25 cm²

The area of the compound shape is 71.25 cm².

Can u guys PLEASE ANSWER this question ASAP.

Answer:

x = -14

Step-by-step explanation:

The expression to write in this problem is:

"the sum of x and 12 equals the sum of half of x and 5"

We have:

- The sum of x and 12 is: $x+12$

- The sum of half of x and 5 is: $\frac{1}{2}x+5$

So, the equation to write in this problem is

$x+12=\frac{1}{2}x+5$

We solve it as follows:

1) First, we subtract $\frac{1}{2}x$ from both sides, and we get

$x-\frac{1}{2}x+12=\frac{1}{2}x-\frac{1}{2}x+5\\\frac{1}{2}x+12=5$

2) Then, we subtract 12 from both sides:

$\frac{1}{2}x+12-12=5-12\\\frac{1}{2}x=-7$

3) Now we multiply both sides by 2:

$\frac{1}{2}x\cdot 2=-7\cdot 2\\x=-14$

So, this is the solution.

Using law of cosines, what is angle X to the nearest degree

Monica [59]

Answer:

$X=68\°$

Step-by-step explanation:

we know that

Applying the law of cosines to the triangle of the figure

$yz^2=xy^2+xz^2-2(xy)(xz)cos(X)$

substitute the given values

$9^2=8^2+8^2-2(8)(8)cos(X)$

Solve for X

$81=64+64-128cos(X)$

$81=128-128cos(X)$

$128cos(X)=128-81$

$128cos(X)=47$

$cos(X)=\frac{47}{128}$

using a calculator

$X=cos^{-1}(\frac{47}{128})$

$X=68\°$
